[0002] The processing of sealing rings is usually carried out by setting rubber in a lower mold and using hot-pressing vulcanization forming by matching the lower mold with an upper mold. In the forming process, in order to prevent the rubber from adhering to the mold, ensure smooth demolding of the product and improve the service life of the mold, it is usually necessary to spray a release agent on the surface of the mold. However, the existing sealing ring processing equipment still has some deficiencies.
